Drinking Pattern May Affect Your Risk of Mortality
A further study led by Gronbaek published in Epidemiology, has revealed that changes in alcohol intake result in corresponding changes in mortality levels. The research found that in a study of 6,644 men and 8,010 women aged between 25 and 98, those who had reduced their drinking from light drinking to none increased their risk of coronary heart disease mortality by 40% and those who had increased from non-drinking to light drinking reduced their relative risk ratio by 29%. “Persons with stable patterns of light and moderate alcohol intake had the lowest all-cause mortality”, claimed the researchers. The findings suggest that non-drinkers may benefit from changing to light or moderate drinking. The aim of this study was to provide a step toward the establishment of a causal association between changes in drinking habits and mortality, while taking possible confounders into account. “It is possible that the alcohol-mortality relation –particularly in the non-drinking group – is confounded by concurrent diseases, traits, or lifestyle factors associated with both level of alcohol intake and with mortality. Moreover, cumulative or irreversible effects of previous alcohol intake may influence mortality after a change in intake”, pointed out the researchers.
